Any tips would be appreciated, or online documentation would be great. Of course the instructions are in Japanese! Just purchased a new Blitz FMIC kit. The smaller of the 2 sold, it is about the size of the Greddy 3 row.
I see... Well you shouldn't worry much, it's pretty straight forward and when you start installing it you'll see the car was meant to have one in there and it will fall into place
BLITZ usual provides decent pictures so along with that just remember there are plenty of us on here that have done them or similar ones so there's help if you get stuck...
